The WCT100xA transmitter IC manages the power transfer by receiving commands from the receiver. Receivers are detected by using either standard protocol methods or Freescale touch sensor technology. Once the mobile device is detected, the WCT100xA controls the power transfer by adjusting rail voltage or phase shift of power stage according to message packets sent by mobile device. To maximize the design freedom and product differentiation, the WCT100xA supports any 5W coil topology capable of supporting WPC Qi-based implementation. In addition, the system supports both WPC and PMA protocols. The WCT100xA also includes CAN/LIN/IIC/SCI/SPI interfaces, over-voltage/current/temperature protection and FOD method to protect from overheating by misplaced metallic foreign objects. It also handles any system fault and operation status, and provides comprehensive indicator outputs for robust system design.

The chip may not function if the high or low pulse width is smaller than 6.25 ns. External clock input rise time is measured from 10% to 90%. External clock input fall time is measured from 90% to 10%. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly. The PLL is optimized for 8 MHz input. The frequency of the core system clock cannot exceed 100 MHz. If the NanoEdge PWM is available, the PLL output must be set to 400 MHz. And the minimum PLL output frequency is 200 MHz for WCT1001A, 240 MHz for WCT1003A. This is the time required after the PLL is enabled to ensure reliable operation. 200 kHz internal RC oscillator is on WCT1001A, 32 kHz internal RC oscillator on WCT1003A. Frequency after application of 8 MHz trimmed. Frequency after application of 200 kHz/32 kHz trimmed.

All blocks size is 64 KB on WCT1001A, 256 KB on WCT1003A. Longer all blocks command operation time for WCT1003A. For byte-writes to an erased FlexRAM location, the aligned word containing the byte must be erased. Typical data retention values are based on measured response accelerated at high temperature and derated to a constant 25°C use profile. Engineering Bulletin EB618 does not apply to this technology. Typical endurance defined in Engineering Bulletin EB619. 33. Cycling endurance represents number of program/erase cycles at -40°C ≤ Tj ≤ 125°C. 34. Write endurance represents the number of writes to each FlexRAM location at -40°C ≤ Tj ≤ 125°C influenced by the cycling endurance of the FlexNVM and the allocated EEPROM backup. Minimum and typical values assume all byte-writes to FlexRAM. 35. The ADC functions up to VDDA = 2.7 V. When VDDA is below 3.0 V, ADC specifications are not guaranteed. 36. When the input is at the VREFL level, the resulting output will be all zeros (hex 000), plus any error contribution due to offset and gain error. When the input is at the VREFH level the output will be all ones (hex FFF), minus any error contribution due to offset and gain error. 37. ADC clock duty cycle is 45% ~ 55%. WCT1001A only supports the maximum ADC clock of 10 MHz and minimum ADC clock of 0.1 MHz, and WCT1003A supports 20 MHz maximum ADC clock and 0.6 MHz minimum ADC clock. 38. Conversion range is defined for x1 gain setting. For x2 and x4 the range is 1/2 and 1/4, respectively. 39. In unipolar mode, positive input must be ensured to be always greater than negative input. 40. For WCT1001A, the first conversion takes 10 clock cycles, 8 clock cycles for the subsequent conversion; On WCT1003A, 8.5 clock cycles for the first conversion, 6 clock cycles for the subsequent conversion. 41. For WCT1001A, the power down current of ADC is 0.1 µA, and 0.02 µA for WCT1003A. 42. For WCT1001A, the VREFH current of ADC is 190 µA, and 0.001 µA for WCT1003A. 43. INLADC/DNLADC is measured from VADCIN = VREFL to VADCIN = VREFH using Histogram method at x1 gain setting. On WCT1001A, typical value is +/- 1.5 LSB, and maximum value +/- 2.2 LSB for INLADC; typical value is +/- 0.5 LSB, and maximum value +/- 0.8 LSB for DNLADC.

Typical +/- 12 mV offset for WCT1001A, +/- 13.7 mV offset for WCT1003A. 47. Typical ENOB is 10.6 bits for WCT1001A, 9.5 bits for WCT1003A. 48. The current that can be injected into or sourced from an unselected ADC input without affecting the performance of the ADC. 49. Typical input capacitance is 4.8 pF for WCT1001A, 1.4 pF for WCT1003A. 50. Typical values assume VDDA = 3.0 V, Temp = 25 °C, fADCK = 1.0 MHz unless otherwise stated. Typical values are for reference only and are not tested in production. 51. To use the maximum ADC conversion clock frequency, the ADHSC bit must be set and the ADLPC bit must be clear. 52. The ADC supply current depends on the ADC conversion clock speed, conversion rate and the ADLPC bit (low power). For lowest power operation the ADLPC bit should be set, the HSC bit should be clear with 1MHz ADC conversion clock speed.

Typical supply current with high-speed mode is 300 µA, typical supply current with low-speed mode is 36 µA on WCT1001A. Maximum supply current with high-speed mode is 200 µA, maximum supply current with low-speed mode is 20 µA on WCT1003A.

Comparator initialization delay is defined as the time between software writes to change control inputs (Writes to DACEN, VRSEL, PSEL, MSEL, VOSEL) and the comparator output settling to a stable level. 1 LSB = Vreference/64. Reference IPbus clock of 100 MHz in NanoEdge Placement mode. Temperature and voltage variations do not affect NanoEdge Placement step size. Powerdown to NanoEdge mode transition. Ttimer = Timer input clock cycle. For 100 MHz operation, Ttimer = 10 ns. For QSPI specifications, all data with xx/xx format, the former is for WCT1001A, the latter is for WCT1003A. fMAX_SCI is the frequency of operation of the SCI clock in MHz, which can be selected as the bus clock or 2x bus clock for the device. WCT1001A supports maximum 1.5 us pulse filtered, and WCT1003A supports maximum 2 us pulse filtered. The master mode IIC deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves acknowledge this address byte, then a negative hold time can result, depending on the edge rates of the SDA and SCL lines. The maximum tHD_DAT must be met only if the device does not stretch the LOW period (tSCL_LOW) of the SCL signal. Input signal Slew = 10 ns and Output Load = 50 pF Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty. 76. A Fast mode IIC bus device can be used in a Standard mode IIC bus system, but the requirement tSU_DAT ≥ 250 ns must then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, then it must output the next data bit to the SDA line trmax + tSU_DAT = 1000 + 250 = 1250 ns (according to the Standard mode IIC bus specification) before the SCL line is released. 77.

Automotive Wireless Transmitter Controller, Rev. 1.0, 08/2014 Freescale Semiconductor 21 Figure 1. System Efficiency on Freescale A13 Reference Board Note: Power components are the main factor to determine the system efficiency, such as drivers and MOSFETs. Figure 2 shows the active charging area of the Freescale WCT100xA A13 transmitter reference solution — transmitter well charges receiver load at different X/Y offsets. For this test, the low power receiver is used as the test receiver with constant 700 mA loading and 3 mm Z gap between transmitter surface and receiver surface. Figure 2. Active Charging Area on WCT100xA A13 Transmitter Reference Solution 3.2 Standby Power The purpose of the standby mode of operation is to reduce the power consumption of a wireless power transfer system when power transfer is not required. There are two ways to enter standby mode. The first is when the transmitter does not detect the presence of a valid receiver. The second is when the receiver sends only an End Power Transfer Packet. In standby mode, the transmitter only monitors whether a receiver is placed on the active charging area of the transmitter or removed from there. Automotive Wireless Transmitter Controller, Rev. 1.0, 08/2014 22 Freescale Semiconductor It is recommended that the transmitter’s power consumption in standby mode meets the relative regional regulations especially for “No-load power consumption”. 3.3 Digital Demodulation In order to optimize system BOM cost, WCT100xA solution employs digital demodulation algorithm to communicate with receiver. This method can achieve high performance, low cost, and very simple coil signal sensing circuit with fewer external components. 3.4 Foreign Object Detection WCT100xA solution employs flexible, intelligent, and easy-to-use FOD algorithm to ensure accurate foreign metal objects detection. With Freescale FreeMASTER GUI tool, FOD algorithm can be easily calibrated to get accurate power loss information especially for very sensitive foreign objects. 4 Device Information 4.1 Functional Block Diagram This functional block diagram just shows the common pin assignment information by all members of the family.

The recommended bypass configuration is to place one bypass capacitor on each of the VDD/VSS pairs, including VDDA/VSSA. Ceramic and tantalum capacitors tend to provide better tolerances. Automotive Wireless Transmitter Controller, Rev. 1.0, 08/2014 36 Freescale Semiconductor • Bypass the VDD and VSS with approximately 10μF, plus the number of 0.1μF ceramic capacitors. • Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VDD and VSS circuits. • Take special care to minimize noise levels on the VDDA and VSSA pins. • It is recommended to use separate power planes for VDD and VDDA and use separate ground planes for VSS and VSSA. Connect the separate analog and digital power and ground planes as near as possible to power supply outputs. If an analog circuit and digital circuit are powered by the same power supply, you should connect a small inductor or ferrite bead in serial with VDDA trace. • If desired, connect an external RC circuit to the RESET pin. The resistor value should be in the range of 4.7 kΩ – 10 kΩ; and the capacitor value should be in the range of 0.1μF – 4.7μF. • Add a 2.2 kΩ external pull-up on the TMS pin of the JTAG port to keep device in a restate during normal operation if JTAG converter is not present. • During reset and after reset but before I/O initialization, all I/O pins are at input mode with internal weak pull-up. • To eliminate PCB trace impedance effect, each ADC input should have a no less than 33pF/10 Ω RC filter. • To assure chip reliable operation, reserve enough margin for chip electrical design.

Do not place an analog trace in parallel with digital traces. Place an analog ground trace around an analog signal trace to isolate it from digital traces. • The decoupling capacitors of 0.1μF must be placed on the VDD pins as close as possible, and place those ceramic capacitors on the same PCB layer with WCT100xA device. VIA is not recommend between the VDD pins and decoupling capacitors. • The WCT100xA bottom EP pad should be soldered to the ground plane, which will make the system more stable, and VIA matrix method can be used to connect this pad to the ground plane. • As the wireless charging system functions as a switching-mode power supply, the power components layout is very important for the whole system power transfer efficiency and EMI performance. The power routing loop should be as small and short as possible. Especially for the resonant network, the traces of this circuit should be short and wide, and the current loop should be optimized smaller for the MOSFETs, resonant capacitor and primary coil. Another important thing is that the control circuit and power circuit should be separated. 6.3 Thermal Design Considerations WCT100xA power consumption is not so critical, so there is not additional part needed for power dissipation. However, the power inverter needs the additional PCB Cu copper to dissipate the heat, so good thermal package MOSFET is recommended, such as DFN package, and for the resonant capacitor, C0G material, and 1206 or 1210 package are recommended to meet the thermal requirement. The worst thermal case is on the inverter, so the user should make some special actions to dissipate the heat for good transmitter system thermal performance. 7 References and Links 7.1 References • WCT1001A/WCT1003A Automotive A13 Wireless Charging Application User’s Guide (WCT100XAWCAUG) • WCT1001A/WCT1003A Transmitter Library User’s Guide (WCT100XALIBUG) • WCT1001A/WCT1003A Run-Time Debug User’s Guide (WCT100XARTDUG) Automotive Wireless Transmitter Controller, Rev. 1.0, 08/2014 38 Freescale Semiconductor • WPC Low Power Wireless Transfer System Description Part 1: Interface Definition Version 1.1 7.2 Useful Links • freescale.com • freescale.com\wirelesscharging • www.wirelesspowerconsortium.com Automotive Wireless Transmitter Controller, Rev. 1.0, 08/2014 Freescale Semiconductor 39 How to Reach Us: Home Page: freescale.com Web Support: freescale.com/support Information in this document is provided solely to enable system and software implementers to use Freescale products.
